It is ditlicult to make light advertising plants of great dimensions on high masonry, in using the known arrangements of the incandescent electric lamps. These difticulties are increasing the more extended the surfaces become, on which the incandescent electric lamps are to be arranged. The extended surfaces require especially extended entries in order to resist the immense pressure of the to wind and in order to go along the surfaces for repairing damages. It is necessary to repair from time to time the electric coiuiucting material and the lainp-holders and the incandescent electric lamps are frequently to 11$ be interchanged. Up to the present time therefore the surfaces were equipped with gangways and guides, on which the trimmers had access to the incandescent lamps.

My present invention permits avoiding the E necessity of going along the lamp-tables and avoiding extended entries and gangways.

The lamps are no more arranged on tables.

In order that my invention may be thoroughly understood, I will now proceed to 71 describe the same in the following specification.

Referring to the drawings: Fig. 1 is a front elevation showing the arrangement of the lamps on a net suspended so from a chimney.

Fig. 2 is a side elevation of Fig. 1.

Fig. 8 is a front elevation showing the lamps on single wires suspended from a chimney.

Fig. 4- is a side elevation of Fig. 3.

Fig. 5 shows in front elevation an incandescent electric lamp with protecting cage interposed on a wire and the corresponding part of a transverse rod.

Fig. 6 is an elevation showing the arrangement of the lamps on a net which is suspended in a chimney or mast.

Fig. 7 is a side elevation of Fig. 6.

According to the invention the network which carries the lamps is movable. This network is conducted over pulleys or suspended on pulleys so that it can be moved towards the attendants in order to interchange the lamps.

tion, in which the net is suspended on chim ney 7 and terms a closed loop. The net conof longi udinal strips each composed of five longitudinal. wires 2, and oi transverse wires 4 tied together with the longitudinal wires. The strips 2 each pass over an upper pulley and over a lower pulley 5 and term each a closed loop. The transverse wires are arranged only on the frontside it adver tisements haveto be arranged only on the front side. It however advertisements have to ngcd also on the rear-side, the transverse i extend also over the rear-side 6 and tied there together with the longitudinal wires. in order to interchange the lamps 1 the strips on the front-side of the net pulled down so that running over pulleys and 3 they ascend on the rear-side.

a To facilitate the manipulation, the'network may be subdivided into any desired number of vertical strips. The network shown in Fig. 1 is subdivided into four strips, carrying on the iront'side the lamps which form the characters A and O. The pulleys 3 at the top-end are suspended to a horizontal. rod 8, adapted to be lifted and lowered by a winch 11 through ropes 1O guided over pulleys 9. To each rope 10 a heavy mass-12 is suspended the upward movement oi which at the bulging in of the not under the pressure exerted U by the wind is limited by an abutment 13. The winch 11 is designed to be used at the mounting of the lamps and at repairs. The heavy masses 12 are designed to maintain the net stretched to a certain degree and to allow a certain bending of the wires 26 under the pressure of the wind this bending being limited by the abutment 18. It is necessary that the wires can yield in order that from the tangential component of a certain bending curve the tensile-stress of the wires and ropes may be accurately determined by calculation in order that the safety of the installation against windpressure be ensured by correct dimensioning of the wires.

In some cases it might be desirable to lower certain groups of lamps independently of other lamp groups. Such an arrangement is shown in Figs. 3 and 4, each wire 2 being guided over a separate upper pulley 3 and over a separate lower pulley 5. To each lower pulley a heavy mass 14 is attached to stretch the wire 2. Each heavy mass 14 is guided between a pair of bars 15, only the guide bars for the extreme heavy mass at the left side of Fig. 3 being shown in Fig. 3.

As the vertical wires 2 are not connected the one with the other by transverse wires each wire 2 can be lowered separately. The lamps 1 are interposed in the longitudinal wires 2 in the manner shown in Fig. 5, and they are distributed so that they produce the desired character, for example E as shown in Fig. In order to maintain at uniform distance apart the longitudinal wires 2 which have no transverse connection a transverse rod 18 is provided which, as shown, in Fig. 5, has ring-shaped enlargements 18. These enlargements 18 are of such diameter that the corresponding lamp 1 with its protecting cage can freely pass through the same, when it is being lowered. The transverse rod 18 is suspended by means of ropes 16 on the horizontal rod 8, as shown in Each lamn 1 has a protecting cage 21 in the top portion 20 of which the lamp holder 28 is mounted to which the electric cable is connected. The protecting cage is interposed in the wire 2 by means of eyelets hooked over hooks 29 at the corresponding ends of the portions of the wire 2. The cable 27 and the wire 2 are connected by a protecting sleeve 19.

In Fig. 1 the letter is already formed on the net work and this net work is passed in its entirety over rollers 3 and 5. In the form of construction shown in Fig. 3 a separate roller or pulley is provided for each wire.

It is not necessary to arrange the network, as shown in Figs. 1 or 3. The longitudinal wires 2 of the net might also be attached at the upper end to the upper transverse rod 8, the lower ends of the wires 2 being connected by a transverse rope 23 as shown in Fig. 6. The lower end of the net is for example attached by two ropes 10, 10 guided over pulleys 5, 5 from which they'ascend on the rear to pulleys 25 and descend from these pulleys 25 to a winch 11. To the upper end of the net two ropes 10, 10 are attached which are guided over pulleys 9 to a winch. The two winches may be united so that by their operation the net is lowered on the frontside and raised on the back in passing along the attendants.

In order to ensure that the net adopts the form of a loop, indicated by the dash-linecurve in Fig. 7 the ropes 10 are removed from the pulleys 5 prior to the beginning of the manipulation. The net is moved away from the chimney 7 by means of a cross beam 26 such a distance that the lamps do not touch the chimney when they are ascending on the back.

In all forms of construction the lamps may have separate current supplying wires and wires for returning the current, or the net may be used for returning the current. The'latter arrangement is more practical as the formation of hoar-frost and ice on the net is prevented by the heating due to the return-current.

Vhat I claim is:

1. A light-advertising-plant, comprising in combination an upper transverse rod, means for suspending said transverse rod to a strong support for instance a chimney so that said transverse rod can be raised and lowered, a number of pulleys suspended on said transverse rod, an equal number of pulleys fixed on the ground, endless wires guided over said upper and lower pulleys, and incandescent lamps fixed on said endless wires so that they form characters and signs.

2. In a lightadvertising-plant as specified in claim 1 in combination with the endwires, spacers between said wires.

3. In a light-advertising-plant as specified in claim 1 in combination with the endwires, spacers between said wires eong of transverse bars having ring-shaped cnhngeinents one for each endless wire of such diameter that said incandescent lamps can freely pass through said ringshaped en largements.

1-. In a light-advertising-plant as specilied in claim 1 in combination with the endwires, pacers between said wires consisting of transverse bars having ring-shaped enlargements one for each endless wire of such diameter that said incandescent lamps can freely pass through said ring-shaped enlargements, and protecting cages one for each incandescent lamp.

In testimony whereof I affix my signature.
